Hello!

Note that when seeing an odd number of negatives next to each other, it will remain negative, while having an even number would be positive. For example, -- is +, while --- is -.

Based on this information, we can rewrite the equation below.

2-1/8-7/4

Let's rewrite 7/4 out of 8.

2-1/8-14/8

2-15/8

Let's rewrite 2 as an improper fraction.

16/8-15/8=1/8

Therefore, our answer is 1/8.

Explanation:
When u try to find the lengths of a right triangle you use the formula c = √(a² + b²). When you use the formula you take your TWO smallest numbers which is 12.5 and 30 you would plug it in the formula and solve and when you solve you should get 32.5.
